  --enable-path=PaTh      (NOTE: this value isn't used if confstr() and _CS_PATH
                          are available, or if <paths.h> defines _PATH_DEFPATH)
                          Use PaTh if PATH isn't specified in the environment
                          when the shell starts.  A value without . in it is
                          safest.
                          The default value is \"/bin:/usr/bin:/usr/ucb\"."
ac_help="$ac_help
  --enable-shell={sh,ksh} Specify the kind of shell that is to be built (the
                          default is ksh).  Specifiying sh compiles out:
                          command line editing (emacs/vi), history,
                          a bunch of aliases, [[ .. ]], select, let,
                          brace-expansion, extended globing (*(..|..), etc.),
                          co-processes, some special environment variables
                          (ie, MAIL, MAILCHECK, MAILPATH, RANDOM, SECONDS,
                          TMOUT)."
ac_help="$ac_help
  --disable-emacs         Compile out emacs command line editing (by default,
                          this is compiled in for ksh, compiled out for sh)."
ac_help="$ac_help
  --disable-vi            Compile out vi command line editing (by default,
                          this is compiled in for ksh, compiled out for sh)."
ac_help="$ac_help
  --disable-jobs          Compile out job control support.  If your system
                          doesn't support job control, this will automatically
			  be compiled out."
ac_help="$ac_help
  --disable-brace-expand  Compile out brace expansion code (a{b,c} -> ab ac)
                          (by default, this is compiled in for ksh, compiled
                          out for sh).  Brace expansion can also be disabled
                          at run time (see set +o braceexpand)."
ac_help="$ac_help
  --enable-history={no,simple,complex} By default, simple history is used for
                          ksh, no history is used for sh.  \`simple' means
                          history file is read on start-up, written when shell
                          exists.  \`complex' means history files are updated
                          after each command so concurrent shells read each
                          other's commands.  Note: \`complex' history doesn't
                          work well across NFS; also, it requires the mmap()
                          and flock() functions - if these aren't available,
                          \`simple' history is automatically used."
ac_help="$ac_help
  --enable-posixly-correct Enable if you want POSIX behavior by default
                          (otherwise, posix behavior is only turned on if the
                          environment variable POSIXLY_CORRECT is present or by
                          using \"set -o posix\"; it can be turned off with
                          \"set +o posix\").  See the POSIX Mode section in the
                          man page for details on what this option affects.
                          NOTE:  posix mode is not compatable with some bourne
                          sh/at&t ksh scripts."
ac_help="$ac_help
  --enable-default-env=FILE Include FILE if ENV parameter is not set when
                          the shell starts.  This can be useful when used with
                          rsh(1), which creates a non-login shell (ie, profile
                          isn't read, so there is no opertunity to set ENV).
                          Setting ENV to null disables the inclusion of
                          DEFAULT_ENV.  NOTE: This is a non-standard feature
                          (ie, at&t ksh has no default environment)."
ac_help="$ac_help
  --enable-silly          [A silly option]"
ac_help="$ac_help
  --enable-swtch          For use with shell layers (shl(1)).  This has not
